摘要翻译:
由Halpern和Teague发起的理性秘密共享研究将秘密共享中的秘密重构视为一种博弈。研究表明,参与方(当事方)可能拒绝透露其份额,因此重建可能失败。此外,拒绝透露份额可能是一个政党的主导策略。在本文中,我们把秘密共享看作是一个更大的行动/对策的子行动或子对策,其中秘密打开了消费某种公共物品的可能性。我们声称参与者的效用将取决于这种共同利益的性质。特别是,Halpern和Teague的情景对应于一种相互竞争的、可排除的共同利益。我们考虑了这种公共利益是不可竞争和不可排除的情形,并找到了许多自然纳什均衡。我们列举了秘密共享的几个应用来证明我们的主张,并给出了相应的场景。在这种情况下,秘密共享方案有利于在社会中达成权力共享协议。我们还陈述非重建可能对这个社会有益,并举了几个例子。

英文摘要:
The study of Rational Secret Sharing initiated by Halpern and Teague regards the reconstruction of the secret in secret sharing as a game. It was shown that participants (parties) may refuse to reveal their shares and so the reconstruction may fail. Moreover, a refusal to reveal the share may be a dominant strategy of a party. In this paper we consider secret sharing as a sub-action or subgame of a larger action/game where the secret opens a possibility of consumption of a certain common good. We claim that utilities of participants will be dependent on the nature of this common good. In particular, Halpern and Teague scenario corresponds to a rivalrous and excludable common good. We consider the case when this common good is non-rivalrous and non-excludable and find many natural Nash equilibria. We list several applications of secret sharing to demonstrate our claim and give corresponding scenarios. In such circumstances the secret sharing scheme facilitates a power sharing agreement in the society. We also state that non-reconstruction may be beneficial for this society and give several examples.
